We propose to investigate the gas dynamics in the 150 kpc region surrounding M87 with seven 20 ks pointings around the existing deep XMM-Newton observation. We will determine the dynamical properties of the gas across the surface brightness edge that lies 90 kpc north of M87 and extends 140 degrees in azimuth. We will derive accurate gas density and temperature profiles across the edge and at all azimuths around M87 and use them to derive the gas pressure distribution and the gas velocity responsible for producing the edge. Using standard hydrostatic analysis of the fields away from the edge, we will measure the gravitating mass profile. Thus, we will determine the dynamical properties of the gas to compare to observations of AGN outbursts at smaller radii.
